Benthic Macroinvertebrate Recovery After Wastewater Treatment Plant Upgrades: Implications for Biomonitoring

open access: yesRiver Research and Applications, Volume 42, Issue 4, Page 824-836, May 2026.
ABSTRACT During the past decade, major upgrades have been made to the Kitchener and Waterloo wastewater treatment plants (WWTPs) in the Grand River watershed in Ontario, Canada. As part of efforts to evaluate the effectiveness of these investments (>$450 M CDN), a benthic macroinvertebrate (BMI) monitoring program was initiated by sampling upstream and

Wind Turbine Model Validation Is Improved by High‐Resolution, Measurement‐Derived Inflows

open access: yesWind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT There is an increased need for accurate validation of turbine models used by original equipment manufacturers to fine‐tune prototypes and predict power performance and maintenance needs while avoiding costly warranty payouts. Perhaps the most substantial source of uncertainty in typical wind turbine model validation procedures is the use of ...

Securing the Participation of Safety-Critical SCADA Systems in the Industrial Internet of Things [PDF]

open access: yes, 2016
In the past, industrial control systems were ‘air gapped’ and isolated from more conventional networks. They used specialist protocols, such as Modbus, that are very different from TCP/IP.

A Framework for Phasor Measurement Placement in Hybrid State Estimation via Gauss-Newton

open access: yes, 2013
In this paper, we study the placement of Phasor Measurement Units (PMU) for enhancing hybrid state estimation via the traditional Gauss-Newton method, which uses measurements from both PMU devices and Supervisory Control and Data Acquisition (SCADA ...

The Untapped Hydropower Potential of World's Cities

open access: yesEarth's Future, Volume 14, Issue 5, May 2026.
Abstract Many large cities around the world experience frequent power outages and yet have an abundance of tall buildings and experience rainfall. This represents a unique and scalable opportunity for cities to capture the intermittent rainwater at high elevation and convert the potential energy into electricity for rechargeable batteries at street ...

Capacitance Technology Enables Automated Feeding, Improved Expansion, and Higher Throughput of CAR‐T Cell Stirred‐Tank Bioreactor Cultures

open access: yesBiotechnology Journal, Volume 21, Issue 4, April 2026.
Graphical Abstract and Lay Summary This article demonstrates how capacitance probes can be applied to single‐patient (autologous) manufacturing processes within the cell and gene therapy (CGT) industry by using CAR‐T cells as a case study. Current CGT processes require operator intervention to sample, monitor and harvest each batch which increases ...
